It doesn't matter if the whole stadium was laughing and cheering all in a fit of black humor. It's a disgusting display and embarrassment to our city and Winston is completely justified for calling out everyone partaking in it.

Except fans were cheering a nice first down catch and run by Charles.

Then they applauded as Cassel walked off of the field (this is just a common courtesy of fans when a player is injured).

Then they cheered as Quinn came onto the field.

Winston is just projecting his anger at the fans rather than on his team-mates and himself for their terrible 1-4 start.
